Fatty food goes bad while frozen, and it's not because of bacteria or fungi. It doesn't rot, it just get a bad taste. So food does age even when frozen. I'm not fat, but even skinny people has some fat in their body. Isn't our brains made up mostly from fat?
And bacteria doesn't die from being frozen, that's why it's no help to freeze food that have almost gone bad.
That link seems to be music so I doubt it can explain how to thaw a living body.
It is true the fatter the food, the less time it remains edible after freezing. Bacteria becomes dormant in freezing temperatures, yes. Parasites, the other raw food concern, can be killed in cold temperatures.
The link, although a joke image, was meant to depict a fibrillator.
Cold enough temperatures can preserve even fat tissue, however. The problem isn't freezing a body and keeping it from decaying. There are places you could go even now and request to be cryogenically frozen until the technology is created to unfreeze you. You won't age frozen, because age derives from your biological use, wear, and tear. It's not like they'll thaw you and suddenly you'll look 300.
Fatty foods going bad while frozen is because the freezers we have in our homes simply don't get cold enough to accomplish what you're talking about.
